6.20 Stauroderus scalaris (Fischer von Waldheim, 1846) Ch: SIE; ERL: LC; P-V; %C: 33.81; ER: 890-2840 m; Ph: VII-X S. scalaris is the most common orthopteran species in the MNP, occurring in about a third of the whole study area. This taxon is widespread in warm montane and subalpine grasslands, with only some individuals recorded at high elevations (> 2600 m). According to the available data, the specimen observed at 2840 m (Passo Vallanta, Pontechianale; 27/08/2020; DG) represents a new altitudinal record for S. scalaris in Italy and in the whole W-Alpine region.
